It is spring ride. We had the spirings and one axle replaced 6 years ago. It has been used on a small cow herd, in fact we just pulled it today. It has a diamond plate floor with anti-slip ridges in it. All of the lights have been replaced with sealed beam lights and they all work, including the inside light. The trailer is a 75', but you wouldn't know it. It is a good solid trailer. We are located in Illinois. Give me a call if you would like any more info. on it or are interested in looking at it. Thanks!
